<div class="markdown_content"><p>Oder ein komplette PRG in AS programmieren... da tut man sich meiner Meinung nach bei Schrittketten etwas leichter.</p> <p>Ansonsten kannst du dir in der Funktion mal einen Breakpoint setzen, dann werden die die Werte in diesem Moment angezeigt.</p> <p>Gruß Chris</p></div>
